ELECTRIC TEMPERATURE-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 328,156, dated October13, I885.

Application filed June 4, 1885. Serial No. 167,674.

- Suffolk and State of New York, have invented certain new and usefulImprovements in Elec tric Temperature-Regulators; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, which formpart of this specification.

The object of this invention is a new and useful device for changing theair in rooms, halls, churches, and other structures byproviding asheltered chamber open to the outer atmosphere, and a passage between itand the place in which it is desired to regulate the temperature, andmeans to open and close such passage automatically by the employment ofan electric current.

Figure 1 is a front view of my improved temperature-regulator. Fig. 2 isa cross-sectional elevation of the same, through the line a; a: ofFig. 1. Fig. 3 is a plan View of a por tion of the same, the top of theframe removed to show the parts clearly. Fig. 4' is a detail view of apart of the movable slat b and its bearing. Fig. 5 is a front view of anarrangement of thermometers adapted to be used with my regulator.

Similar letters of reference indicate like parts in all the drawings.

A is a frame of suitable size to fit into the opening designed, havingoutwardly-projecting portions y z, and roof B, which is made preferablyof glass, to form the outer chamber, D,which is inclosed on all sides,but open at the bottom. This frame A is usually made to fit into apartof a window or other suitable opening, and has the roof B far enoughfrom it to leave the outer chamber, D, as large as may be desired.

In the frame A, Iarrange vertical stationary slats a a, permanentlyfixed in position diagonally across the frame, as shown clearly in Fig.3, and leaving open spaces between them. The drawings show these slats aa made of glass, which is the material I prefer to use when it isdesired to admit the light, although other materials may be used. Intothe open spaces between the fixed slats ca, I fit movable slats b b,which are pivoted between the fixed (No model.)

slats so that they may be'turned straight across the frame A to open thespaces between the fixed slats, as is indicated by the dotted lines inFig. 3, and these slats b b are of such size that when they are turneddiagonally across the frame they will close the spaces between the slatsa a. The object of having these pivoted slats stand straight across theframe when the spaces are to be open, is to have them present the leastsurface to the currents of air passing through the openings so that theymay not be turned thereby. These pivoted slats b b are preferably madeof metal, which is the material indicated in the drawings, and I usethin brass plates, which I have found will produce good results. Intothe top and bottom of these slats I fit little pintles f, preferablymade of steel, and into the upper and lower parts of the frame I drivelittle metal bearings e for the pintles, preferably made of brass, as isshown in Fig. 4, by which arrangement the pivotal movements can be madewith very little friction.

To the tops of the slats b [2 arms (I d are attached, which pivot themall to the horizontal rod 0, and this rod 0 is pivotally connected atone end to the compound lever g h by means of the arm 0,- and to a partof the frame A a spring, 20, is attached to draw the rod 0 in onedirection to hold the slats b b diagonally across the frame A and closethe openings between the fixed slats.

To the arm 71. ofthe compound lever an armature, i, is attached, nearwhich is located the electro-maguet E in such position that when thearmature is attracted to the magnet the lever will draw the rod 0 farenough to bring the slats b 1) straight across the frame. One wire, it,runs from the magnetEto the battery Z, and a wire runs from the batteryto the bulb of a thermometer. The other wire, j, runs from the magnet tothe tube of the thermometer, where it is hermetically sealed at anydesired degree of temperature indicated.

In case only one standard of temperature is provided for, only onethermometer need be employed, arranged as above described; but ifseveral standards of temperature are to be provided for, I employ morethan one thermometer, arranged as shown in Fig. 5.

O is a frame on which two thermometers are placed side by side, each ofthem having a wire, preferably platinum, fused into their tubes m m at adetermined degree of temperature, in the drawings shown at 68 and 72,respectively. These tube-wires meetat t, and are carried to a bindingpost, ass, where they are brought into electrical connection with thewire j.

The bulb wires 0 0 are independently brought to the switch-buttonspp,which buttons are placed in contact distance, radially, of the switch q,ally connected through the binding-post r, wire is, and battery Z, andwire is, to the mag net E, and thereby an electric circuit may be formedthrough either thermometer.

I have shown two thermometers only; but more may be arranged on theframe 0 and employed in the same manner, where it is likely that greatervariations of temperature may be required at differenttimes, as in sickroomsor hospitals, &c'.

The advantage of using a separate thermometer for each standard oftemperature is that each thermometer can then be made airtight and themercury retained in vacuum, by which oxidation is retarded, and the thermometers' will last a long time.

The thermometer-frame O is adjuste'don that level in the room at whichit is desired to have the temperature kept evene. 9., on the level of abed, &c. r I

The operation is as follows: When the temperature rises in the room tothe maximum point desired, the mercury in the thermometer-tube rises,and when it touches the tubewire it closes the electrical circuit,whereby the magnet E becomes excited and attracts the armature i, whichoperates the levers g' h, drawing the rod 0, and holding the slats bb'in position straight across the frame A, un'clos'ing' the openingsbetween the fixed slats a a and and this switch q is electricallowingthe cold air to pass into the room and the warm air to pass off .throughthe outer chamber, D, until the temperaturehas been re is required tooperate the device.

Having'thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. A temperature-regulator consisting of an I outer chamber, 1), frameA, slats a aand b b,

a nd'the rod 0 and its con nections,in combination with a suitableelectric device for operating the same, arranged substantially asdescribed and shown.

2. A temperature-regulator consisting of a frame, A, chamber u fixedslats a a, movable I slats b b, and rod 0 and its connections, incombination with a magnet, E, and battery Z, electric'ally connectedwith a suitable thermometer, substantially as described and shown.

3. A temperature-regulator consisting of a chamber, D, frame A,- havingvfixed slats'a a, movable slats b b, and rod 0' and its connec tions, incombination with two or more therm'ometers connected from their tubeselectrically through the magnet E, and battery Z,wit-h the switch 1, thebulb of each thermometer connected independently with a button, as p,

substantially as described and shown.
